F1Represents restricted stock granted under the issuer's 2010 Equity Incentive Award Plan. The restricted stock vests in three equal annual installments beginning on March 2, 2017, provided that the reporting person remains employed by the issuer as of each vesting date.
F2Represents performance-based restricted shares ("PSAs") granted under the issuer's 2010 Equity Incentive Award Plan. The number of PSAs earned is based on the issuer's achievement of relative total shareholder return ("TSR") measured versus the MSCI US REIT Index over a three-year performance period ending December 31, 2018, and the number of shares earned may range from 25% to 175%. The PSAs are earned as follows: (i) 20% of the PSAs are earned upon TSR achievement in year one of the performance period, (ii) 20% of the PSAs are earned upon TSR achievement in year two of the performance period, (iii) 20% of the PSAs are earned upon TSR achievement in year three of the performance period, and (iv) 40% of the PSAs are earned upon a cumulative TSR achievement over the three-year performance period, subject to the reporting person's continued employment with the issuer at the end of the three-year performance period. The PSAs are granted and issued at 175% of the target amount.
F3The reporting person is a co-trustee of the family trust.
